Answer:
D
Step-by-step explanation:
Geometric sequence has to do with a pattern of multiplication, and D has a pattern of times 4 if that makes any sense
The answer is D, i.e. the system was solved via elimination
If you multiply the first equation by 5, the system becomes
If you sum the two equations, you get
And so if you substitute the second equation of system A with this new equation, you'll get system B.
Answer:
22
Step-by-step explanation:
because i swiched the x's to the 7 and multipled
From the right triangle formed, the adjacent side to the angle of elevation is 5 miles and the vertical change in elevation is the opposite side. From the trigonometric function, tangent of an angle,
tan 12° = x / 5 miles
The value of x from the equation is 1.06 miles. Thus, the vertical change in elevation is 1.06 miles.
